SAIL.

EPECIFIC'A'IION forming part of Letters Patent No. 397,589, datedFebruary '12, 18823.

Application filed September 6, 1888. gerial No. 284,702i (N0 model) Toall whom, it may concern.-

Be it known that I, WILLIAM PORTE'RFIELD CUTLER, a citizen of the UnitedStates, residing at Baltimore, in the State of Maryland, have inventedcertain new and useful Improvements in Sails, of which the following isa specification.

My invention relates to sails, particularly to the j ib-sails ofsailingwessels. Heretofore, usually, the head and foot-bias parts ofthis class of sails have been united at their ends by a lap-seam, at theouter end of which scam the elew was secured, and the sail was formed ofstrips of canvas which extended in parallel widths diagonally across thesail from the foot or bottom to the head or top of the same. The biassections of canvas forming the head and foot portions of such sails wereso out that the breadths or strips forming them extended in a paralleldirection with the leech and foot ropes. Subsequently jib-sails wereformed by making the sail in a single section or piece on a bias, sothat the ribs or lengths of canvas composing the sail were short andextended diagonally across the sail along its entire length from head orstay rope to leech and from the head or stay rope to the footrope. Inaddition to thus making the sail on a bias, are-enforcing bias-cut pieceor gusset was seen red transversely across the widest or middle portionof the sail, extending 011 each side from the elew to the head or stayrope. Parting of the sail. along the seams extending transversely of thesail to the elew often occurs, in which case the sail is rendereduseless. Injury to the j ib-sails of a vessel usually occurs at a timewhen the vessel under full headway, and frequently during a gale, whenrepairs of this nature cannotbe judiciously attempted.

The object of my invention is to so form the sails that the defectsabove mentioned will be obviated, as will be hereinafter more fullydescribed.

In the drawings, Figure 1 a view of a jibsail constructed in accordancewith my iniprovenients, and Fig. 2 is a view of the gusset orstrengthening-strip.

In carrying out my invention I form the applied to other forms oisailsof two parts,

A and B, which parts A B are formed of widths or strips, 0 and I), ofcloth, the seams of which run in reverse or diverging directions fromthe middle line of the bolt-rope II and completed sail to the leech-ropeE and foot-rope F.

The portions A B of the sail are united at their wider ends by a doubleseam, and in additi on to this double seam a gusset or strengtliening-piece, I, is employed and extends on both sides of the sailfrom the elew to the middle of the head or stay rope, the clew beingsecured to the sail after the gusset I has been stitched to place in theusual manner.

In the prior constructions of this class of sails, where the longestcloths and scams were employed at and near the widest part of the sail,I use conqmraiively the shortest cloths or strips, and consequentlyshorter seams. Further, by my construction I greatly reduce the biasupon the stay or head rope, the wider ends of the portions receiving aconsiderable portion of the bias, thereby rendering the sail less liableto stretch out of proportion in hoisting the sail or during the pitchingof the ship. Besides these advantages, my construction presents morebias on the leech and foot,

where the sail must give more or less in order to make a perfectsettingsail.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, isv A reversible diagonal out twopart sailformed of widths or strips of cloth, 0 and D, the seams of which run inreverse or divergin g directions from the middle line of the boltrope IIor, completed sail to the leech-rope E and foot-rope .F of the sail, thediverging seams in the respective portions of the sail being parallel,as set forth.

In testimony whereof I at'fix in y signature in presence of twowitnesses.
